Versuchsvorschrift

In a 200 ml three-necked flask were placed 3.6 g of 2-amino-6-methoxybenzothiazole and 6.0 g of ethyl p-toluenesulfonate, and the mixture was stirred at 120° C. for 3 hours. To the resulting mixture was added acetone and the mixture was stirred at room temperature for 1 hour. The crystals were filtered under reduced pressure and washed with acetone to give the desired compound.
